T all whom it may concern:

Be it known that I, ISAAC SNOW, a citizen of the United States, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented an Improvement in Feeler Mechanisms for Looms, of which the following description, in connec- "tion with the accompanying drawings, is a Specification, like characters on the drawings representing like parts. p

This invention relates to feeler mechanisms for loomswhereby the filling'may be replenished from time to time. In that type of feeler mechanisms wherein the feeler is given a movement in adirection longitudi nally of the shuttle to effect replenishment, it is the usual practice 'to adjust the feeler a predetermined distance from the rear or head endof the bobbin to properly cooperate with the filling and to call the change when the filling is substantially exhausted. In view of the'diversity of kinds offilling wound bobbins or carriers used in some looms, it consequently becomes necessary to adjust the feeler each time the character of the filling wound bobbins 0r carriers is changed, and especially is this the base where the same loom employs at one time filling wound bobbins or carriers wherein the windings at the initial stage are more fiat or cylindrical than the filling wound bobbins or. carriers used at other times in the'loom,

wherein the windings are more abrupt or r are of the short conical wind. For instance, if the feeler is adjusted to suit the long flat wound filling carriers or bobbins, and then the same loomv employs the short conical wound filling carriers or bobbins, the feeler is liable tov call the change when 40 a working supply of filling is Still present in the short. conical winds and consequently produce much waste. K One of the objects of the present invention is to provide a feeler mechanism in which the feeler shall be so constructed that without adjustment it may be used'with either character of filling wound bobbins or carriers, and in accordance with the present thereon a preventer tip which,when the fill- 5 7 Application filed August 6, 1923.

invention the feeler has pivotally mounted ing on the bobbin" presented to the feeleris substantially exhausted but there still remains a working supply in the short conical wind, the preventer tip is caused to engage the short conical winds and, prevent 5 premature side swipe. movement of the feeler. r

The various features and new combination of parts pertaining to-the presentinvention will best be understood from the following description and the accompanying drawings of one good, practical form thereof. a In the drawings:

Fig. 1 is a perspective view of a feeler' mechanism containing the present invention, some of the partsbeing broken away;

Fig. 2 is a rear end perspective view of thefilling-engaging end of the feeler;

Fig. 3 is a plan view showing theiaction of the feeler when a working supply of fill ing is present in. the shuttle on a detecting eat; V.

Fig. 4: is a'similar view showing'the action of the pt'eeler mechanism when thefilling portion ofthe filling carrier or bobbin prese'nted to the feeler is substantially exhausted of filling but there yet remainsa working supply oftheshort conical wind; 7

Fig. 5 is a plan view of the feelerand 'the relative position of partswhen the filling of the short conical wind has reached or nearly reached a degree of substantial exhaustion; and 1 v j W Figfiis a view similar to that of Fig. 5 showing the'filling-"of the short conical wind substantially exhausted and the feeler partaking of its sideswipe movement.

Since the present inventionis more directly concerned with the feeler itself rather than-with the replenishing mechanism or the means between the feeler and the replenishing mechanism for efiecting replenishment of f filling, it has not been deemed necessary to show herein the filling 95 replenishing mechanism or details of the means for setting it in operation when the feeler is moved longitudinally of the shuttle on a detecting beat. The details of these parts may be similar to those already wellknown.

In the present illustration of the invention the feeler is. shown as of the inclined type which is mounted to enter the shuttle on a detecting beat in a direction inclined to the longitudinal axis of the shuttle, but the invention itself and its advantages may be utilized in other types of feeler mechanisms wherein the feeler is moved longitudinally of the shuttle to call for a change of filling.

Extending from the front of the loom frame is the shipper stand 1 to which the feeler mechanism may be connected in usual manner. In the present instance the feeler stand 2 is provided with a slot 3 through which passes the bolt 4 for securing the feeler stand in the desired adjusted position.

Mounted at the front of the feeler stand is the rocking bearing 5 supported for rocking movement by a bracket 6 secured to the feeler stand by a bolt 7 At the rear portion of the feeler stand is a guideway 8 which forms a support for a slide 9 to which is connected a transmitter 10 asso-' ciated with the means for initiating replenishment of filling when the feeler partakes of its sideswipe movement.- The slide 9 9 has the opening 11 through which the feeler 12 extends, the front end portion of th feeler being passed through an opening in the rocking bearing 5. Secured to the feeler 12 is the bridge 13 between which and the rocking bearing 5 is interposed a spring 1 1 normally tending to hold the feeler in its rearward feeling position, and the rear portion of the feeler is provided with a filling engaging end 15 preferably provided with a roughened surface or tooth 16,- the construction being such that should a working supply of filling be present in the shuttle on a detecting beat, the roughened or toothed end of the filling engaging portion 16 will sink into thev filling and prevent movement thereof in a direction longitudinally of the shuttle. Should, however, the portion of the filling carrier or bobbin which is presented to the filling engaging end of the feeler be substantially exhausted of filling, the feeler will be moved longitudinally along the filling carrier and call the change. The parts and constructions so far described and as shown are and may be substantially the same as shown and described in the patent to Edward S." Stimpson, No. 1,309,226, dated July 8, 1919.

as usual, and similarly the shuttle 18 may be provided with an opening 19 which registers with the opening in the front wall of the shuttle box on a detecting beat to permit the feeler to enter the shuttle and feel for the filling. The shuttle 18 is provided with the usual bobbin'holding jaws 20 which engage the usual rings 21 on the filling carrier or bobbin 22.

Pivotally mounted on the feeler at 23 is the preventer tip 24 which extends laterally to each side of the feeler and, as shown in the present instance, the feeler preventer 2 1 is provided with a filling engaging tooth 25 at one side of the feeler and a bobbin or filling engaging portion 26 at the opposite side of the filling engaging end of the portions between which the filling engag-" ing end 15 of the feeler extends. The preventer tip may be stamped out of sheet metal conveniently and bent as described to provide the filling-engaging tooth 25 and the bobbin or filling engaging portion 26. The edge portions of the connecting wall 27, as at 28 and 29, form a stop for limiting the free swinging movement of the pre venter tip.

Should a filling carrier or bobbin of the long or fiat filling wind beemployed in theshuttle, the feeler stand is adjusted to position the feeler for engagement with the filling carrier or bobbin or thefilling thereon at a point some distance from the head of the bobbin, and when the filling is substantially exhausted on adetecting beat the toothed end portion 16 ofthe filling engaging end of the feeler will notbe held from its sideswipe movement, and the feeler will call for a change of filling as usual. Should a filling carrier having short conical winds be employed in the shuttle, as indicated in Fig. 4, and the: portion ofthe filling carrier or bobbin be presented to the filling engaging end of the feeler with" the filling thereon substantially exhausted, as indicated in Fig. 4, the toothed end por-; tion 16 of the feeler will tend to slip longitudinally along the filling carrier orbobbin, but should a working supply of filling be present in the short conical wind adjacent the bobbin head, as indicated in Fig. 2, the toothed end portion 25 of the preventer tip will engage the conical wind and prevent premature movement of the feeler longitudinally along the'filling carrier or bobbin, until, when the filling is substantially exhausted in short eonicalwinds, as indicatetd in Fig. 6, the tooth 25 will no longer hold the feeler from its sideswipe movement and a change of filling will be called.

The engaging end portion 26 of the preventer tip insures a holdingengagement of the tooth 25 of the preventer tip with the short conical winds by coming in contact with the denuded or substantially denuded portion of the filling carrier or bobbin at the opposite side of the filling engaging end of the feeler and causes the tooth 25 to sink into the short conical winds, as indicated in Figs. 4: and 5, until when the reserve supply of filling in the short conical winds has itself become substantially exhansted, as indicated in Fig. 6, the tooth25 will no longer be held by the now substantially exhausted windings of the short conical winds and the feeler will then be free to partake of its sideswipe movement to call for a change of filling,

Thus, without any change in the adjustment of the feeler, the feeler mechanism of the present invention may be employed in connection with either long fiat conical winds of filling on the filling carriers or bobbins or with the short conical winds, without the production of undue waste and without readjustment of the,- feeler.
